succeeded in radiocarbon dating three out of five of the bones tested. The three bones yielded the following dates: (20,030 to 18,100 years BP), (22,890 to 22,400 years BP) and (24,990 to 24,210 years BP). The investigation held between 2012 and 2016 found more than 1,000 human fragments from at least 19 human skeletons.

Due to the skeletons' postures, the site has been confirmed as the first graveyard in the Paleolithic age in Japan.
